ALARM-CLOCK.

SPECIFICATION forming part of Letters Patent No. 283,429, dated August21, 1883 Application filed November 17, 1882. (No model.)

which it pertains to make and use the same.

My invention relates to an improvement in alarm-clocks, and moreparticularly to that class thereof in which the timer and alarmmechanism are isolated from each other, the object being to conceal thelatter, to prevent it from interfering with the action of the timer, andto connect it with the timer by devices of positive action, combiningsimplicity and cheapness of construction with durability and efficiencyin use.

A further object of my invention is to provide means for winding thealarm mechanism without opening the clock-case.

With these objects in view my invention consists in certain details ofconstruction and combinations of parts, 'as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in elevation andpartly in section of a clock embodying my invention, and Fig. 2 is asimilar view of one of the modified forms which the invention mayassume.

The clock-case shown in Fig. 1 of the drawings is composed of a body, A,and a base, B, the former inclosing the chamber O, in which. the timer Dis located, and the latter inclosing the chamber E, in which the alarmmechanism F is placed, the said mechanism, which may be of any approvedconstruction, being preferably inclosed in a case, G, as shown in thedrawings.

The tripping-rod H, consisting of a straight piece of wire, is arrangedto extend through a hole, I, in the floor or partition J, between thechambers G and B. As shown in the drawings, this rod is inclosed in asheath, K,

I attached to the jamb of the body portion of the case, but this sheathmay be dispensed with, y

if desired. The lower end of the rod is at tached to a wire, L, attachedto the pallet M of the alarm mechanism, its upper end being connected tothe outer end of a lever, N, pivoted midway, or nearly midway, of itslength to the front plate, 0, of the timer, the inner end of the saidlever being arranged to bear upon the periphery of the trip-wheel P atits nadir point.

The winding-arbor Q of the alarm mechanism is prolonged and extendedthrough an aperture, R, formed in. the base portion B of the case, andprovided with a winding-ring, S, which latter may be substituted by aknob or any equivalent device. If desired, the alarm mechanism,and thelevers connecting it with the timer, may be located on the other side ofthe clock, as indicated by dotted lines in the drawings.

In the modification shown in Fig. 2 of the drawings the clock-caseis'provided with a chambered top piece, T, in which the alarm mechanismis located, the wire L of the said mechanism being connected to thetimer by means of the same rod and lever, as shown, the inner end of thelever having bearing in this instance upon the periphery of thetrip-w11eel at the zenith point. As shown in this figure of thedrawings, the alarm mechanism is wound by a key inserted through a hole,U, formed in the frontof the top piece. If desired, however, thewinding-arbor may be extended and provided with a ring or knob, asbefore described. It is also apparent that the alarm mechanism and itsconnections may be changed to the other side of the clock.

The constructions shown in Figs. -1 and 2 of the drawings may be furthermodified by dispensing with the chambered base and top portions of theclock and locating the alarm mechanism in the chamber in which the timeris situated, the said mechanism being located above and below and oneither side of the timer, and connected therewith by same levers asshown for theother constructions. Iwould therefore have it understoodthat I do not limit myself to the exact construction shown anddescribed, but that I hold myself at liberty to make such slight changesand alterations as fairly. fall within the spirit and scope of myinvention. t

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an alarm-clock, the combination, with the timer, of alarmmechanism located above or below and on either side thereof, a straighttripping-rod, one end of which is attached to a wire secured to thepallet of the alarm mechanism, and 'a lever pivoted midway, or nearlymidway, of its length to the front plate of the timer, its outer endbeing attached to the other end of the tripping-rod, and its inner endhaving bearing upon the periphery of the tripwheel, substantially as setforth.

2. In an alarm-clock, the combination, with the timer, of alarmmechanism located in a chamber isolated from that in which the timer islocated, a casing for the alarm, a straight tripping-rod extending intothe chamber in which it islocated, and connected with it, and

a lever pivoted midway, or nearly midway, of
